MgAl Oxide Coatings Modified with CeO2 Particles Formed by Plasma Electrolytic Oxidation of AZ31 Magnesium Alloy: Photoluminescent and Photocatalytic Properties

Metals, Journal Year: 2024, Volume and Issue: 14(3), P. 366 - 366

Published: March 21, 2024

MgAl oxide coatings composed of MgO and MgAl2O4 phases were doped with CeO2 particles via plasma electrolytic oxidation (PEO) AZ31 magnesium alloy in a 5 g/L NaAlO2 water solution. Subsequently, up to 8 added. Extensive investigations conducted examine the morphology, chemical phase compositions, and, most importantly, photoluminescent (PL) properties photocatalytic activity (PA) during photodegradation methyl orange. The number incorporated into depends on concentration aluminate electrolyte. However, do not significantly affect thickness, structure, or surface morphology coatings. PL emission spectrum is divided two bands: one 350–600 nm range related structural defects MgO, another much more intense band 600–775 attributed F+ centres MgAl2O4. have significant effect intensity red spectral region, but first increases particles. PA MgAl/CeO2 higher than that pure coating developed electrolyte 2 exhibited highest PA. remained chemically physically stable across multiple cycles, indicating their potential for applications.

Modification of Ti13Nb13Zr Alloy Surface via Plasma Electrolytic Oxidation and Silver Nanoparticles Decorating

Materials, Journal Year: 2025, Volume and Issue: 18(2), P. 349 - 349

Published: Jan. 14, 2025

The dynamically developing field of implantology requires researchers to search for new materials and solutions. In this study, TiNbZr samples were investigated as an alternative popular, but potentially hazardous TiAl6V4. Samples etched, sandblasted, subjected PEO, covered in AgNP suspension. Simultaneously, SEM images taken, the wettability roughness surface measured. AgNPs biological trials. A six-day measurement human fibroblast proliferation was conducted assess biocompatibility, population E. coli S. aureus measured over eight hours. Results showed that PEO is biocompatible with cells promotes growth. However, deposited exhibited only slight effectiveness decreasing bacterial growth first two results suggest method preparation sufficient might promote osseointegration. On other hand, more efficient reliable methods application should be researched.
